A cylindrical portion is provided at one end of a chassis that is housed in the envelope and supports the curved tube-shaped valve and the lighting circuit component, and a screw portion and a vertical slit are formed on an outer peripheral surface of the cylindrical portion. The base is screwed into the screw portion and fixed by means such as adhesive or caulking.

[0005] One of a lead wire led from a bulb or a lighting circuit component is connected to the eyelet terminal of the base, and the other is connected to an opening edge of the base shell. Both of these two lead wires pass through the tubular portion of the chassis, one lead wire is led to the opening of the tubular portion and connected to the eyelet terminal, and the other lead wire has a slit formed in the tubular portion. It comes out and is connected to the base shell.

After passing the lead wire through the cylindrical portion of the chassis, it is necessary to lead the other lead wire connected to the base shell through the slit. There is a problem that the operation of positioning the other lead wire in accordance with the interval between the narrow slits and leading the lead wire is not easy, and the manufacturing operation becomes complicated. The present invention has been made in view of the above-described problems, and provides a fluorescent lamp device that can easily lead a lead wire from a narrow width slit of a cylindrical portion and facilitates a lamp manufacturing operation. Aim.

According to a first aspect of the present invention, there is provided a fluorescent lamp device comprising: a cover on which a bulb and a lighting circuit component are mounted; a tubular portion formed above the cover; and an upper end of the tubular portion. a slit formed in the same width in the longitudinal direction so as upward wider and becomes so-formed triangular notch and continuing from the lower side of the cutout portion; said valve also

In the drawings, reference numeral 1 denotes a saddle-shaped curved tube-shaped bulb, 2 denotes a chassis for holding the bulb 1, and 3 denotes an E26 type mounted on the chassis 2. Reference numeral 4 denotes a cover member made of a synthetic resin, and reference numeral 5 denotes a glove for covering the bulb 1 made of a light-transmitting synthetic resin or glass. The chassis 2 is made of a synthetic resin such as polyethylene terephthalate, and a screw portion 22 to which the base 3 is screwed is engraved on the outer periphery of the upper cylindrical portion 21. Cylindrical receiving portion 2 for holding and fixing the end portion 11 of the saddle-shaped curved tube-shaped valve 1 through the
5, 25, a mounting portion 26 for the lighting circuit component 5 such as a ballast, and a locking portion 27 for locking the bent portion 12 of the curved tubular valve 1
Is provided. The screw portion 22 on the outer periphery of the cylindrical portion 21 has a slit 28 in the longitudinal direction, and a triangular cutout portion 29 is formed on the upper portion of the slit 28.

[0007] A pair of long and short lead wires 13 and 14 are inserted into the cylindrical portion 21 while one long lead wire 1 is inserted.
Reference numeral 3 denotes an eyelet 31 at the top of the base 3, and the other short lead wire 14 is led out from the lower end of the slit 28 and connected to the side surface of the shell 32 of the base 3.

The assembly of the fluorescent lamp having this configuration is performed as follows. First, the bent portion 12 of the saddle-shaped curved tube-shaped valve 1 is locked to the locking portion 27 of the chassis 2, and the ends 11, 11 are fitted to the cylindrical receiving portions 25, 25 and bonded with a silicone adhesive. Fix it. The cylindrical receiving portions 25, 25 may be formed with key-shaped cuts 25A, 25A so as to elastically hold the valve end 11 until the silicone adhesive is solidified. Next, the lighting circuit component 5 such as a ballast is mounted on the mounting portion 26, and the lead wires 13 and 14 are passed through the tubular portion 21, and the shorter lead wire 14.
Is guided into the slit 28 from the notch 29 of the cylindrical portion 21 by a working tool such as a fingertip or tweezers, and is pulled out from a lower portion of the slit 28.

Next, the step 4 of the chassis 2 is covered with the cover 4, and one long lead wire 13 is passed through a hole of an eyelet 31 at the top of the base 3, and the base 3 is threaded into 22 and the base 3 is fixed to the cylindrical portion 21 with an adhesive or caulking. In addition, the other short lead wire 14
Is located at the opening of the shell 32 of the base 3, and these two lead wires 13, 14 are joined to the eyelet 31 at the top of the base 3 and the side surface of the shell 32 by means such as soldering or welding. Then, the fluorescent lamp device is completed by aligning and locking the opening of the globe 5 with the opening of the cover 4.

[0010] In such a fluorescent lamp device, a wide triangular cutout leading to a slit is formed in the cylindrical portion of the chassis at the time of assembling, so that the lead wire led out to the shell side of the base has a wide cutout.
